Flanged container lid for metal cans

ABSTRACT

Appliances are destined for separate storage of two components, at least one of which is a food product, in individual containers. A container lid for a can contains a shell where there is an insert in the form of a reservoir, and a pot installed over the reservoir by a releasable connection. On the bottom edge of the shell there is a joint ring. The shell is attached to the can by at least two locks installed on the external shell surface, and there are additional fixture elements. In a second embodiment, there is a sealed polyethylene cartridge inside the reservoir.

EMBODIMENT

Utility model refers to appliances destined for separate storage of twocomponents, at least one of which representing food product, in twoindividual containers.

In particular, utility model may be applied as a header on standardmetal cans for drinks.

From the state of art the solution on the utility model No. 1137273B65D51/28, 2011, is known, from which the header for a reservoir, namelya threaded bottle, is known; it is characterized by the fact that theheader is configured in a form of a reservoir for storage of components,and s lid with the opening for the reservoir, herewith the collar forinteraction of container with the bottle neck is made on the reservoirshell. The indicated art solution is selected as the closest analog.

The disadvantage of prior art solution is limited functionalcapabilities of usage of the appliance, as well as its low humanfactors.

Technical result of the patented solution is the enlargement offunctional capabilities of the appliance with expansion of applicationand simultaneous increase of convenience in application.

The claimed technical result is achieved as follows.

According to the first embodiment the container lid for metal cancontains a shell where an insert in a form of reservoir is placed, and apot installed over the container is installed by means of releasableconnection. On the bottom edge of the shell there is a joint ring. Theshell is attached to the can by means of at least two locks installed onthe external shell surface. There are additional fixture elements forthe strap on the shell.

According to the second embodiment the container lid for metal cancontains a shell in which the insert in a form of reservoir is placed.Inside the reservoir there is a sealed polyethylene cartridge. Over thereservoir a pot is installed by means of releasable connection. On thelower edge of the shell there is a joint ring. The shell is attached tothe can by means of at least two locks installed on the external shellsurface. There are additional fixture elements for the strap on theshell.

For both variants the following design is possible, when:

-   -   the shell has fluted surface;    -   the lock represents creepers enabled to connect with the flange;    -   the pot is connected with the shell by means of thread        connection.

The technical solution is illustrated on FIG. 1-9.

FIG. 1-1, 1-2 shows assembled container lid on the can, general view,with opened and closed lock, correspondingly;

FIG. 2 shows container lid, general view.

FIG. 3-9 show particular embodiment of the appliance components.

On the shell (1) there is a reservoir (8); according to the secondembodiment it is capable of placement of sealed polyethylene cartridge(3) with filler (biscuits, sweets, nuts, yogurts, etc.) in it. Accordingto the first embodiment the reservoir (8) is destined for storage oftoys, souvenirs, etc.

The reservoir (8) is tightly closed with the pot (2) by means of threadconnection (4). On the shell (1) there are two locks (7) that tightlypress the internal surface of the flange of the aluminum can with drinkto the elastic joint ring (5) situated on the lower internal part of theshell (1) creating sufficient leak resistance and preventing leak of thedrink when walking.

Also, there are two fixture elements (6) on the shell (1) that arerequired for attachment of adjustable plastic strap, and for convenientbearing of the can on the shoulder. On the bottom of the shell (1) thereis a radial riffling in a form of ribbed surface (9) in order to excludeshell spinning in the hand during pot (2) twist-off. The pot (2) in thisconstruction has dual purpose: it is a cover for the shell (1) and areservoir in which the content of the drink metal can may be poured off.On the top of the pot (2) there is a knurling for its convenienttwist-off. The cartridge (3) is made with the protection fromdeformation when pressed from above, during its filling into thereservoir (8). On the top of the cartridge (3) there is a flange (10)destined for leak-proof shut-off, for example, with polyethylene film oraluminum foil. The thread is used for connection of the shell (1) andthe pot (2). The joint ring (5) is an integral part of the shell (1),and is used for pressure tight joint of the shell (1) and aluminum can.The area of the ring (5) that thrusts against the aluminum can is madewith minimum thickness, for example, by means of pressure casting formaximum elasticity of the joint ring surface (5) and maximum firmadherence to the aluminum can. Correspondingly, by means of this jointring (5) the shell (1) provides leak-proof closure for already openedaluminum can. The locks (7) are situated in the bottom part of the shell(1). Design of locks during their closure makes it possible not todeform already opened aluminum can, as when opened the can loses itsrigidity and may be easily deformed with the drink pouring out. Locks(7) are connected with the shell (1) by means of thin neck. As theentire appliance is made of flexible plastics, this neck thicknessallows multiple openings and closure of locks. Locks are closed bypressing on them with fingers. The entire effort of pressing istransmitted to the can flange, that is rigid enough. Also, forwardmovement of the can to the shell takes place during closure of locks dueto the adherence of lock ledges to the can flange making possible thejoint ring (5) to nestle tightly on the aluminum can, and to secure thedrink from pouring out when walking. Fixing of locks on the shell (1) isperformed by means of ledges (11). During lock latching (7) the ledges(11) come into special grooves on the shell (1) and are fixed tightly.Locks are opened with finger tips by prying them up on technologicalcaves in the lock end face.

The proposed technical solution allows extension of functionalcapabilities of the good and is capable to satisfy consumer demands tothe goods of this class.
